一种 较新的聚类算法 Dominant-set 的代码，包括聚类算法的代码和测试代码。该算法最大特点 就是基于图理论的 ，相对于Normalized Cut,计算复杂度低很多，况且能自动决定类的个数 -A relatively new clustering algorithm Dominant-set the code, including the clustering algorithm code and test code. Most prominent feature of the algorithm is based on graph theory, and compared with the Normalized Cut, much lower computational complexity, decision Moreover automatically the number of categories
